Q. 170. How do they that worthily communicate in the Lord’s supper feed upon the body and blood of Christ therein?

A.
As the body and blood of Christ are not corporally or carnally present in, with, or under the bread and wine in the Lord’s supper,[1084] and yet are spiritually present to the faith of the receiver, no less truly and really than the elements themselves are to their outward senses;[1085] so they that worthily communicate in the sacrament of the Lord’s supper, do therein feed upon the body and blood of Christ, not after a corporal and carnal, but in a spiritual manner; yet truly and really,[1086] while by faith they receive and apply unto themselves Christ crucified, and all the benefits of his death.[1087]

[1084] Acts 3:21. Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
[1085] Matthew 26:26, 28. And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.... For this is my blood of the new testament, which is shed for many for the remission of sins.
[1086] 1 Corinthians 11:24-29. And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. For as often as ye eat this bread, and drink this cup, ye do show the Lord's death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
[1087] 1 Corinthians 10:16. The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
